EarthCube Overview
 Geoscience future focus (GEO 2009): Fostering a sustainable future
through a better understanding of our complex and changing planet.
 CIF21 (2012): providing a comprehensive, integrated, sustainable,
and secure cyberinfrastructure (CI) to accelerate research and
education and new functional capabilities in computational and
data-intensive science and engineering, thereby transforming our
ability to effectively address and solve the many complex problems
facing science and society.
 EarthCube Vision (Governance 2014): “… enable transformative
geoscience by fostering a community committed to providing
unprecedented discovery, access, and analysis of geoscience data…”

Project Objective
 Our Conceptual Design project is to design an
EarthCube Enterprise Architecture (EA) to support
EarthCube for facilitating data communication and
human collaboration in pursuit of collaborative
geosciences.
 The designed EA is to assist EarthCube (2012) as:
 A geoscience research engine
 A geoscience resource management platform
 A geoscience computing service provider
 A geoscience education platform
